In order to solve the technical problem, the utility model discloses specifically adopt following technical scheme:

the utility model provides a two connecting rod breaker rotors, its includes that pivot and a plurality of interval set up at the epaxial rotor assembly of commentaries on classics, every the rotor assembly includes connection pad and four through first round pin axle detachable evenly arrange the hammer seat on the connection pad along circumference, every the hammer seat is not connected the one end with the connection pad through second round pin axle detachable connection tup.

Compared with the prior art, the utility model discloses following beneficial effect has:

the utility model discloses a set up the pivot and set up a plurality of rotor assemblies in the pivot interval, wherein the rotor assembly includes that connection pad and four evenly arrange the hammer seat on the connection pad through first round pin axle along circumference, pass through second round pin hub connection tup in the one end that the hammer seat is not connected with the connection pad, hammer seat and connection pad and hammer seat and the equal detachable connection of tup just through the assembly of round pin axle, simple structure and installation are dismantled very conveniently, provide convenience for the change of hammer seat and tup.

Drawings

FIG. 1 is a front view of the present invention;

FIG. 2 is a full sectional view of FIG. 1;

fig. 3 is a schematic structural diagram of the middle hammer head of the present invention.

In the figure: the rotary shaft comprises a rotary shaft 1, a rotor assembly 2, a connecting disc 20, a first pin shaft 21, a hammer seat 22, a second pin shaft 23, a hammer head 24, a balance disc 25 and a spacer bush 26.

Detailed Description

The following detailed description of the present invention will be made with reference to the accompanying drawings and examples.

Referring to fig. 1-3, the utility model provides a two connecting rod breaker rotor, it includes that pivot 1 and a plurality of interval set up rotor assembly 2 in pivot 1, every rotor assembly 2 includes connection pad 20 and four evenly arranges hammer carrier 22 on connection pad 20 along circumference through first round pin axle 21 detachable, every hammer carrier 22 does not pass through second round pin axle 23 detachable connection tup 24 with the one end that connection pad 20 is connected.

Specifically, the section of the hammer seat 22 is H-shaped, one end of the hammer seat 22 is inserted into the connecting disc 20, and the other end of the hammer seat 22 is inserted into the hammer head 24.

The hammer head 24 is in a link shape, and the hammer head 24 is symmetrical along two radial sides, so that the hammer head 24 is the same as the initial installation state when being installed by rotating 180 degrees.

In the scheme, the rotating shaft 1 is arranged, the plurality of rotor assemblies 2 are arranged on the rotating shaft 1 at intervals, each rotor assembly 2 comprises a connecting disc 20, four hammer seats 22 are uniformly arranged on each connecting disc 20 along the circumferential direction, the sections of the hammer seats 22 are H-shaped, so that the connecting discs 20 are inserted at one ends of the hammer seats 22 and are connected with the hammer seats 22 through first pin shafts 21, hammer heads 24 are inserted at the ends, which are not connected with the connecting discs 20, of the hammer seats 22, the hammer heads 24 are connected with the hammer seats 22 through second pin shafts 23, the hammer seats 22 are arranged in the H shapes, so that the connecting discs 20 and the hammer heads 24 are inserted in the hammer seats 22, the stability of the device is effectively improved, the stress of the rotor assemblies 2 is balanced in the rotating process, one end of each hammer head 24 is in a connecting rod shape and is inserted into the hammer seat 22, the other end of each hammer head 24 extends out, the hammer heads 24 are, the single side that corresponds on the tup 24 takes place the striking with the ore, and when wearing and tearing are great need change tup 24, through extracting second round pin axle 23, can continue to carry out the breakage with 24 rotatory 180 installations of tup, has effectively prolonged rotor assembly 2's life, and the installation is dismantled all very conveniently moreover.

Preferably, the section of one end of the hammer head 24, which is not connected with the hammer seat 22, is trapezoidal, and the trapezoidal large end surface is far away from the rotating shaft 1. When the breakage, mainly utilize the striking between tup 24 and the ore to realize the breakage of ore, set the one end cross-section that tup 24 and ore contacted to trapezoidal and trapezoidal main aspects and ore contact, consequently when having certain wearing and tearing, 24 intensity of tup still can satisfy the requirement, simultaneously through the area of contact of increase tup 24 and ore for 24 unit area atress of tup reduce, have effectively prolonged 24's of tup life.

In a preferred structure of the connection disc 20 in the above aspect, balance discs 25 are further welded to two end faces of the connection disc 20, and the balance discs 25 are arranged coaxially with the connection disc 20. Set up balance plate 25 on two terminal surfaces of connection pad 20, play the effect of counter weight power for device stability is better, has improved the intensity of connection pad 20 simultaneously.

Further, a spacer bush 26 is further arranged between every two rotor assemblies 2, and the spacer bush 26 is sleeved on the rotating shaft 1. Make the distance between the rotor assembly 2 adjustable through setting up spacer 26, when carrying out the breakage to different ore, through change different spacer 26 increase or shorten the distance between the rotor assembly 2 can, the suitability is more extensive.

In order to further improve the crushing efficiency, every two adjacent rotor assemblies 2 are arranged in a staggered mode so that the hammer heads 24 are dispersed on different directions of the rotating shaft 1. Arrange every tup 24 and make tup 24 atress more even at rotatory in-process through arranging every tup 24 in the position of difference, more abundant to the breakage of ore, crushing efficiency is higher.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
